Abstract

The invention discloses an anti-running tensioning device, which is characterized by comprising a bracket and a plurality of pairs of tensioning rollers arranged in parallel on the bracket. When the cylinder is jacked up, the coupling piece is driven to move, and after the coupling piece moves, each pair of tensioning rollers is driven to move, and the positioning pieces are arranged at both ends of the tensioning rollers. The invention has novel structure design, strong practicability and good tensioning effect, can effectively prevent the film from deviating during the transmission process, and greatly improves the preparation or processing efficiency of the film.

Description

technical field [0001] The invention relates to the technical field of film processing machinery, in particular to an anti-deviation tensioning device. Background technique [0002] During the preparation or processing of the film, in order to maintain the flatness of the film, a tensioning device needs to be used. The tensioning device in the prior art still has deficiencies, and it is easy to cause wrinkles in the film, which affects the quality of the film product. Therefore, an innovative design of the tensioning device is required. Contents of the invention [0003] In view of the above technical problems, the present invention provides an anti-deviation tensioning device, which has a novel structural design, strong practicability, and good tensioning effect, which can effectively prevent the deviation of the film during the transmission process and greatly improve the preparation of the film. or processing efficiency. [0004] In order to achieve the above object, ...
